It is believed that the many advantages ofa tonsillectome constructed in accordance Withthe present invention will be readily understood, and

although the preferred embodiment of the invention is as illustrated and described, itis to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall Within the scope of the invention as claimed.

. What is claimed is;

1. A tonsillectome comprising a barrel, afton sil receiving cup'on one end of the barrel and communicating with said barrel, a piston opera able in the barrel for creating a suction in, the cup for drawingthe tonsil'thereinto, a snare in the cup for severingthe tonsil, a rodconnected to the snare and extending'slidably intofthe piston, means for connecting the rodto the pistonfor actuation thereby after independent initial movement of said piston, and means for actuating the piston.

I 2. A tonsillectome comprising a barrel, a tonsil receiving cup mountedon the barrel and communicating therewith, a piston operable in the barrel for creating a suction in the cup and drawing the tonsil thereinto, a snare in the cup for severing the tonsil, means connecting the snare to the piston for actuation thereby, and means tor actuating the piston. t

3. A tonsillectome comprising a barrel, acannula mounted longitudinally on oneend of the barrel, a tonsil receiving cup on the free end of the cannula, saidcup communicating with the barrel, a piston operable in the barrel for creating a suction in the cup for drawing a tonsil thereinto, a snare mounted in the cup for severing the tonsil, a rod ,slida'bly mounted'in the cannula and extending slidably into the piston, means for piston, and means for releasably locking'the piston against movement in one direction; I
